Compiling Ruby code into a class file and trying to load it afterwards leads to "LoadError: use java_import to load normal classes" if it includes a rescue command.

test.rb

puts 'hello world' rescue nil

compiled and run with

jrubyc test.rb
jruby -e "load 'test.class'"

leads to

LoadError: test.class is not compiled Ruby; use java_import to load normal classes
   load at org/jruby/RubyKernel.java:955
  <top> at -e:1

This happens with the current 9.0.5.0 snapshot and all previous 9.0.x versions.

Well that's weird.

I can't reproduce this on 9.1 (ruby-2.3 branch) so it's possible I fixed it with other jrubyc fixes.

[] ~/projects/jruby $ jrubyc test.rb

[] ~/projects/jruby $ jruby -e "load 'test.class'"
hello world

[] ~/projects/jruby $ cat test.rb
puts 'hello world' rescue nil

I ran into this issue as well. It's a serious blocker for me.

I just tested whether a JVM version difference in my stack could be the problem, but it seems that did not affect it.

The execution environment is the Docker official jruby:9.0.5.0-jre image. I originally built the jar on a Mac with Java 1.7.0_45 and rvm jruby-9.0.5.0. I retried building under the Docker official jruby:9.0.5.0-jdk image, but got the same error:

LoadError: uri:classloader:/pacer-model/core.class is not compiled Ruby; use java_import to load normal classes
